Confidential Computing API C++ Client Library
An idiomatic C++ client library for the Confidential Computing API, a service to create challenges and verify attestation responses.
While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.
Quickstart
The following shows the code that you'll run in the google/cloud/confidentialcomputing/quickstart/
directory, which should give you a taste of the Confidential Computing API C++ client library API.
#include "google/cloud/confidentialcomputing/v1/confidential_computing_client.h"
#include "google/cloud/project.h"
#include <iostream>
int main(int argc, char* argv[]) try {
if (argc != 3) {
std::cerr << "Usage: " << argv[0] << " project-id location-id\n";
return 1;
}
namespace confidentialcomputing = ::google::cloud::confidentialcomputing_v1;
auto client = confidentialcomputing::ConfidentialComputingClient(
confidentialcomputing::MakeConfidentialComputingConnection());
// auto const project = google::cloud::Project(argv[1]);
auto const parent =
std::string{"projects/"} + argv[1] + "/locations/" + argv[2];
auto result = client.CreateChallenge(parent, {});
if (!result) throw std::move(result).status();
std::cout << result->DebugString() << "\n";
return 0;
} catch (google::cloud::Status const& status) {
std::cerr << "google::cloud::Status thrown: " << status << "\n";
return 1;
}
Main classes
The main class in this library is confidentialcomputing_v1::ConfidentialComputingClient
. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock confidentialcomputing_v1::ConfidentialComputingClient
when testing your application.
